The upper surface configuration of the packing ring 420 of the top in wind portion 40.
The lower surface of first annulus 512 is configured at the lower surface than central portion 511 and the following table of the second annulus 513
The upper opening position in face.Therefore, the lower surface of cap 51 has in the second top plate in the radial zone of the first annulus 512
The recess that axially upside is recessed upward in portion 622.Moreover, the second top plate portion 622 is configured with the inside of recess.In this way,
There is the recess for containing the second top plate portion 622 by cap 51, the axial width of clamping section 50 can be made turn into required
Min..Therefore, it is possible to reduce the axial dimension of air-supply arrangement 1, and it can aid in the lightweight of air-supply arrangement 1.
Fastening part 52 is inserted in the fixing hole 610 of the mounting hole 510 of cap 51 and the hub body part 61 of wheel hub 322
In.Thus, cap 51 and hub body part 61 are fixed in fastening part 52.That is, cap 51 and motor part 30 are fixed in fastening part 52.And
And the axle 321 of motor part 30 and fastening part 52 be in the inner side of the first cylindrical portion 612 of hub body part 61, in the axial direction every
Gap and relative.
By such structure, air supplying part 40 is on the above-below direction of axial direction by the flat board of the vibrating part 62 of wheel hub 322
Second annulus 513 of maintaining part 623 and cap 51 clamps.That is, air supplying part 40 axial direction above-below direction on by motor part 30
And clamping section 50 clamps.In this way, by clamping air supplying part 40 and fixation from upper and lower, can be by air supplying part 40 and the jail of motor part 30
Admittedly it is fixed.Therefore, air supplying part 40 can be stably rotated, therefore the air-supply efficiency of air-supply arrangement 1 improves.
In addition, in the air-supply arrangement 1, cap 51 has the multiple hole portions 515 penetrated vertically.Specifically,
Six hole portions 515 are configured with one annulus 512.Also, six hole portions 515 are configured with the second annulus 513.Thus,

Opening position diametrically overlapping with the second top plate portion 622 is placed in, by the rotating part 32 of motor part 30, air supplying part 40 and is clamped
The durability for the rotary body that portion 50 is formed improves.
When motor part 30 drives, air supplying part 40 and clamping section 50 rotate together with rotating part 32.Thus, by each flat
The viscous drag and centrifugal force on the surface of plate 410, the air-flow for being radially oriented outside is produced in the near surface of each flat board 410.Cause
This, produces the air-flow for being radially oriented outside in the axial gap 400 between flat board 410.Then, the gas on the top of shell 20
Via the air entry 202 and upside flat board 411 of shell 20 and the passage 70 of central flat 413 towards each axial gap 400
Supply, discharged from the air outlet 201 for the sidepiece for being arranged at shell 20 to the outside of air-supply arrangement 1.
Here, the axial width of each flat board 410 is about 0.1mm.On the other hand, the axial length of each axial gap 400 is
About 0.3mm.Preferably axially the axial length in gap 400 is 0.2mm~0.7mm.If the axial length of axial gap 400 is big,
When air supplying part 40 rotates, produced in the upper surface of air-flow caused by the lower surface of the flat board 410 of upside and the flat board 410 in downside
Interval is vacated between raw air-flow.Then, the static pressure in axial gap 400 will not become big, it is possible to can not discharge sufficient wind
Amount.It is difficult to reduce the volume of air-supply arrangement 1 in the axial direction also, if the axial length of axial gap 400 is big.Therefore, at this
In air-supply arrangement 1, the axial length of axial gap 400 is located in the range of 0.2mm~0.7mm.Thereby, it is possible to improve axial direction
Static pressure in gap 400 and obtain sufficient draft capacity, and air-supply arrangement 1 can be made more to be thinned.
Upside flat board 411 and central flat 413 have passage 70.Therefore, in upside flat board 411 and central flat
In 413, being configured at the outer ring-like portion 72 in the outside of passage 70 turns into the air-supply region that air-flow is produced near surface.The opposing party
Face, lower flat 412 do not have passage 70.Therefore, in the upper surface side of lower flat 412, than the portion contacted with packing ring 420
Region entirety in the outer part is divided to turn into air-supply region.That is, in the upper surface side of lower flat 412, in the axial direction with upside flat board
411 and the region that overlaps of passage 70 and rib 73 of central flat 413 and the area that is overlapped in the axial direction with outer ring-like portion 72
Domain turns into air-supply region.Also, in the lower face side of lower flat 412, than the part that is contacted with flat board maintaining part 623 in the outer part
Region entirety turn into air-supply region.In addition, also produce air-flow in the lower surface of flat board maintaining part 623.
In this way, the air-supply region of lower flat 412 is bigger than the air-supply region of upside flat board 411 and central flat 413.Cause
This, can be than other axial directions in the axial gap 400 being configured between the central flat 413 of lower side and lower flat 412
Improve static pressure in gap 400.
Downward by the air-flow of air entry 202 and multiple passages 70 in each axial gap 400 by radially
Outside attracts.Therefore, with being weakened by the air-flow of passage 70 downward.In the present embodiment, by by downside
Air-supply region in flat board 412 is set as the air-supply region being more than in upside flat board 411 and central flat 413, is being configured at most
The air-flow than other axial gap the last 400 is produced in the axial gap 400 of lower section, attraction passes through downwards the gas of passage 70
Stream.Thus, the gas of sufficient amount is also supplied to the axial gap 400 for being configured at bottom.As a result, more improve air supplying part
Air-supply efficiency in 40.
In the impeller rotation for making to have multiple blades produces the conventional air-supply arrangement of air-flow, by caused by impeller
Air-flow leaks in the upper and lower end parts of impeller.Also, the axial length regardless of air-supply arrangement, it can all produce letting out for the air-flow
Leakage.Therefore, if being thinned air-supply arrangement, influence of the leakage in air-supply arrangement entirety can become big, therefore efficiency of blowing
Decline.On the other hand, in the air-supply arrangement 1 of present embodiment, because the near surface in flat board 410 produces air-flow, therefore
The air-flow is not easy to leak along above-below direction.Therefore, even in the situation for the axial length for reducing the air supplying part 40 for producing air-flow
Under, it is not easy to produce the decline of air-supply efficiency because of the leakage of air-flow.That is, even in the situation for being thinned air-supply arrangement 1
Under, it is not easy to cause efficiency decline of blowing.
Also, in the air-supply arrangement with impeller, produce and periodically make an uproar because of the shape of blade, piece number, configuration etc.
Sound.However, the air-supply arrangement 1 produces air-flow by the viscous drag and centrifugal force on the surface of flat board 410, thus with impeller
Air-supply arrangement compare, quietness is excellent.
Also, from the viewpoint of PQ characteristics (air volume-static pressure characteristic), compared with the air-supply arrangement with impeller, have
Static pressure of the air-supply arrangement 1 of multiple flat boards 410 in low air quantity region is big.Therefore, air-supply arrangement 1 is adapted to compare can only discharge
Used in high density housing of the air-supply arrangement with impeller than relatively low air quantity.As such housing, such as enumerate individual
The electronic equipments such as people's computer.
In the present embodiment, upside flat board 411 and all central flats 413 have passage 70.Thus, all axles
Connected in the axial direction via air entry 202 and passage 70 with the space of the top of shell 20 to gap 400.
